GLOS'URE FOR CNTAINERS Appiiation. med `July 24,

Collapsible tubes intended to contain toothpaste, shaving cream, c oldcream, vaseline, Vand other paste-like or semi-Huid materials havecommonly been provided with detach- 5 able screw caps. Caps of thischaracter have to be removed to of the tube and such Caps are frequentlydropped and lost or mis-placed, beside which theyv are l'diiiicult Vtoscrew on accuratelyand easily because the threads become crossed inattempting to replace the cap. Y

yThe object'o my invention is to provide an improved cap for use on anycollapsible tube or like containers, such as commonly einployed forcontaining and dispensing toothpaste, shaving cream, cold cream,vaseline, and other semi-liquid ingredients, which will be adapted foropening and closing in a semiautomatic manner, when manipulated by theuser, without possibility of detachment of the cap from the neck ornozzle of the collapsible tube. -A

My invention insures against loss or misplacing the cap and also insures'rapid and easy opening and closing thereof, while afording a tightand'satisfactory closure which y prevents the escape of the contents ofthe collapsible tube, when the tube is packed in a traveling bag orothery container with other articles, and at other times.

It will be understood that the principle involved in the presentinvention is not limited to use in connection with collapsible tubes andto illustrate the use of the device in'oth er connections, I have shownand described hovv the invention may be usedas a cap for an automobileradiator. Other uses will be apparentsfrom the following description ofthe in- 40 vention. f

'adapted to telescope over the outer end 6 of 1931. Serial No. 552,987,

Fig. 5 is a plan view of the ring employed in connection with the formshown in Fig. 4; and Y Fig. 6 is a part side elevation, part sectional yview showing the invention applied to an automobile radiator nozzle.

The collapsible tubeto which my improved cap is shownas applied, appearsat 1 and has a neck or nozzle 2 which is provided in its end V with anorifice 8 through hich the toothw paste, shaving cream, col-d cream orthe like maybe extruded on pressing the tube 1, as usual.

The neck or nozzle 2 is provided with a rib 4 extending longitudinally*thereof and ter- 65' minating at acircumferential flange 5 located nearthe end 'of said nozzle, leaving a' free end part 6 on said nozzle whichis adapted to enter the improved cap.

The guide key rib 4 has a cross notch or indentation? disposed near theouter end of said-rib to co-operate with means on the improved cap. Thewalls'of the notch 7 arek tweenthe notch and the ange 5, the purpose ofwhich will be described later. The inner end of the rib 4 may extend tothe shoulder 8 of the tube l, as shown in Fig. 1, or said rib may beprovided with a shoulder 9, as shownl in Fig. 2, the purpose of theseconstructionsl being to arrest 1the operating ring for the cap duringthe opening ymovement of the device.

Sli'dable on, and snugly iitting the neck or rnotch 11 that receives therib 4 so that dur- 85 ing the sliding niovementsof the ring '10,' saidring is guided on the tube, prevented from binding thereon, and theswingfor the cap is therebydirected to the notch v7. 90

f A cap 12 has a short lever or arm 13V which is pivoted to the ring 10by a wire or pin 14 whose ends are held in holes 14 drilled in the ring,as shown by dotted lines in Figs. 3 and 5. Lever 13 hasan extension ortoe 15 95 which is adapted to enter the notch 7 when the ring 10 ismovedalmost to the outer end of the nozzle 2, for the purpose of camming thecap 12 down into position where it is 10e the nozzle. The lower face ofthe toe 15 is curved at 15.

The lever 13 has a surface 16 which is adapted to slide or ride on theface of the rib 4 when the ring is drawn toward the tube l. This slidingaction positively hol-ds the cap 12 parallel to the nozzle 2 and outoi'. the way so that the dispensing end of the nozzle can be used. VJhen the ring 10 is drawn outwardly, the tip 15, and the curved face 15of the lever, due to engagement with the wall of the notch 7, cam thelever and swing the cap 12 downwardly to close the dispensing end of thenozzle; that is to say,-the reciprocating movement given to thismanipulative ring causes the cap to be alternately actuated into and outof its closure position.

The cap is of shell-like construction and adapted to telescope over theend 6 vof the nozzle. i

Preferably, there will be provided a suitable cork inner face orgasketl? or'the cap to eiiectually seal the end of the nozzle.

It is desirable to provide a snap catch or locking device to hold thecap 12 in closed position. Such device may comprise a nib 18 on the part6 and an indentation 19 on the cap.

Then the cap is closed, it preferably rests against the outer face ofthe flange 5, which ange also serves as a stop when the ring 10approaches its oi'itermostor extreme travel position, as previouslyexplained.

A suitable linger piece or projection 2O is provided on the cap toenable it to be readily released prior to sliding the ring 10 toward thetube 1. lll/*hen the slidable ring 10 is placed intermediate either ofits extreme travel positions, the toe 15 will ride on the top face ofthe key 4 and thus int-erlockingly hold the hinged cap 12 against tiltaround its pivot 14.

In Figs. 4, 5, I have illustrated the manner in which an additional rib2l may be provided on the nozzle or tubular neck 2, in diametricallyopposite disposition to the rib 4 for the purpose of balancing the ringto lessen the tendency ot the ring to bind on the Vnozzle 2. The i'ing10, if such construction be employed, will have an internal notch 22 toslide on the rib 21 ust as the notch 11 slides on the rib 4. Y

In Fig. 6, I have illustrated the manner in which the principle of theinvention may be applied to the nozzle or nipple of an automobileradiator, for while I am aware that present-day practice calls for flatcaps for automobile radiators, nevertheless the present invention iswell adapted for use as a quick-opening and closing radiator cap. Theonly change which need be made is to provide on vthe interior of thedevice an in* ternally screw threaded ring or part 23 which will -screwon the threaded nipple on the radiator, said nipple being receiverwithin the tubular part 24, which corresponds to thenozzle 2. In thisform of the invention, the

construction is the saine as previously del "will serve as a closure forthe orilice of the nozzle, or, for disposition in open position relativeto said nozzle-orifice.

2. In a closure 'for the nozzle of a container, the combination with anozzle having a.

longitudinal rib, ot a ring slidable on said nozzle and being guided bysaid rib, said rib being provided with a camming notch, i

and a cap provided with a lever hinged to said ring and bodily carriedby, and shiftable with, said ring, said lever having a part which is incontact with the rib and maintains the cap alongside the nozzle when thering is retracted, said lever being provided with a projection which isadapted to cooperate with said camming notch to eliect opening orclosing of the cap when the ring is in a given position of its travel. l
